Get ADC Value

\i I ? A byte::port

Parameter	Type	Range	Description
port	byte	0 ... 3	logical port name

Returns the value of any of the 4 ADC (Analog Digital Converter) ports defined as "Analog In" in the "I/O Settings" section of iLCD Manager XE's "Settings" page.

• The DPC3050's ADCs have a resolution of 12 bits, resulting in a value range of decimal 0 ... 4095 (0xFFF) where 0 is an input voltage of 0V and 4095 is an input voltage of 3V or 3.3V, depending on the value of the supply voltage of the iLCD Controller.
• The DPC3080's ADCs have a resolution of 10 bits, resulting in a value range of decimal 0 ... 1023 (0x3FF) where 0 is an input voltage of 0V and 1023 is an input voltage of 3.3V, the value of the supply voltage of the iLCD Controller.
• The DPC3090's ADCs have a resolution of 12 bits, resulting in a value range of decimal 0 ... 4095 (0xFFF) where 0 is an input voltage of 0V and 4095 is an input voltage of 3.3V, the value of the supply voltage of the iLCD Controller.

Response:

[ACK] value [ACK]

Response Example

[ACK][01][A8][ACK]

This response means the requested ADC currently has a value of 424 (0x1A8).
